Question

我在this example之后使用Node.js上的swagger和directline开发聊天机器人：（https://github.com/Microsoft/BotBuilder-Samples/tree/master/Node/core-DirectLineWebSockets）

每次我向机器人发送消息时，我都会收到多个已发送消息的响应。

示例：

消息已发送1

回应1

消息发送2

回应2

消息已发送3

回应3

用例类似于this question，但是使用websocket。

（DirectLineJS receiving copies of Bot replies）

发送消息：

// send message to bot
  function sendMessages(client, conversationId, utterance) {

        logger.debug("*** SEND A MESSAGE ");

        client.Conversations.Conversations_PostActivity(
                    {
                          conversationId: conversationId,
                          activity: {
                               textFormat: config.activity.textFrormat,
                               text: utterance,
                               type: config.activity.type,
                               from: {
                                     id: callSid
                               }
                          }
                    }).catch(function (err) {
                          logger.error('Error sending message:', err.statusText);
                          callback(null,err);
                    });
  }

接收活动：

  function startReceivingWebSocketClient(streamUrl, conversationId) {

        logger.debug('Starting WebSocket Client for message streaming on conversationId: ' + conversationId+ ' , watermark: '+waterMark);

      var ws = new (webSocket.client)();

      ws.on('connectFailed', function (error) {
        logger.debug('Connect Error: ' + error.toString() );
      });

      ws.on('close', function(){
        logger.debug('Connect Close: ' + error.toString());
      });

      ws.on('connect', function (connection) {

        logger.debug('WebSocket Client Connected');
          connection.on('error', function (error) {
              logger.debug("Connection Error: " + error.toString());
          });
          connection.on('close', function () {
              logger.debug('WebSocket Client Disconnected');
          });
          connection.on('message', function (message) {
              // Occasionally, the Direct Line service sends an empty message as a liveness ping
              // Ignore these messages
              if (message.type === 'utf8' && message.utf8Data.length > 0) {

                  var responseMessage = JSON.parse(message.utf8Data);

                  if(responseMessage.watermark > waterMark)
                  {
                    logger.debug("responseMessage.watermark > waterMark     "+responseMessage.watermark +">"+ waterMark);
                     var activities = responseMessage.activities;
                     activities = activities.filter(function (m) { return m.from.id == config.directLine.from.id });
                     activities = activities.filter(function (m) { return m.conversation.id == conversationId });
                     if(activities.length>0)
                     {
                           waterMark = responseMessage.watermark;
                           logger.debug("************** attività: "+JSON.stringify(responseMessage));
                           sendResponse(activities);
                     }

                  }
              }
          });
      });

      ws.connect(streamUrl);

  }

DirectLine客户端从websocket接收来自bot的多个响应
